Even though he is mentally challenged, Charlie has a real job at a real store. He thinks he is very good at his job, and thinks he has many friends there. Mr. Gordon works at a Plastic factory as a janitor in the book. On the other hand, in the movie, Charlie works at a bakery. The bakery is owned by Mr. Donner, whom Charlie is very fond of.
As for his friends, in both stories, Charlie thinks he has many. And he does have many. Most of them are just fake. In the book, Charlie’s friends persuade him to drink a little too much when they’re out and that leads him to make a fool out of himself. In the same way in the movie, Charlie’s friends just hang out with him to get a good laugh. However, in the book, Charlie didn’t realize it that quickly, nor did he really do anything about it. The movie shows that whenever one of his so called friends would make fun of him he would argue a bit after the procedure was completed.
